肺炎を契機に発見された成人先天性肺気道奇形

Congenitial Pulmonary Airway Malformation in an Adult with Pneumonia

先天性肺気道奇形（CPAM）は，新生児期までに呼吸障害を呈することが多い．無症状で経過し肺炎で発見されることもあるがまれである．われわれは，成人まで無症状で経過し肺炎を契機に発見されたCPAMの1例を経験したので報告する．

Congenitial pulmonary airway malformation （CPAM） most commonly present respiratory distress in the prenatal or neonatal period, but may rarely be asymptomatic and is incidentally found in adult patients with acute or recurrent pneumonia. Herein, we report a case of a 26-year-old asymptomatic adult male patient with pneumonia of the right lower lobe. He was also found to have multiple cystic lesions in the same lobe which was suspected to be CPAM, and the right lower lobectomy was performed.
